Hidden meltwater found deep in Antarctic coastal waters reveals stronger climate impacts

June 5, 2026 feature Hidden meltwater found deep in Antarctic coastal waters reveals stronger climate impacts Hannah Bird Author Gaby Clark Scientific Editor Robert Egan Associate Editor Freshwater from melting Antarctic glaciers may be influencing the Southern Ocean in ways scientists have largely overlooked. New research, published in Frontiers in Marine Science, has found that glacial meltwater is not confined to the ocean's surface, as previously assumed, but can also be detected much...

Two decades of data show that climate change is transforming Biscayne Bay to be warmer, saltier and more acidic

Two decades of data show that climate change is transforming Biscayne Bay to be warmer, saltier and more acidic Stephanie Baum Scientific Editor Robert Egan Associate Editor Climate change and sea level rise are altering the chemistry of Biscayne Bay in ways that could threaten South Florida's coastal ecosystems, water resources, fisheries, and recreation, according to a study led by scientists from the University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science and...

The ocean's health may depend on a tiny microbe inside fish

The ocean's health may depend on a tiny microbe inside fish A hidden alliance between fish and gut bacteria may be quietly helping regulate the oceans—and even the global carbon cycle. - Date: - May 31, 2026 - Source: - University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science - Summary: - A surprising new discovery suggests that tiny microbes living inside fish may be helping shape the chemistry of the world’s oceans. Scientists found evidence that bacteria in the guts...

Research project provides new estimates of greater amberjack abundance in U.S. South Atlantic, Gulf of America

Research project provides new estimates of greater amberjack abundance in U.S. South Atlantic, Gulf of America Sadie Harley Scientific Editor Andrew Zinin Lead Editor A multi-year research project has provided new insight into greater amberjack. The Greater Amberjack Count was led by Sean P. Powers, Ph.D., fisheries ecology professor and Director of the Stokes School of Marine and Environmental Sciences of the University of South Alabama. A team of 20 scientists from more than a dozen...

Fish-microbe partnership may influence ocean health by making carbon-trapping minerals

The article discusses a study that explores the relationship between the gut microbes of a fish and global ocean processes. The research suggests that symbiotic bacteria may support calcium carbonate precipitation in the Gulf toadfish, which could have implications for ocean chemistry and the marine carbon cycle. The study, published in PLOS Biology, provides new insight into how marine ecosystems help regulate ocean chemistry and the marine carbon cycle.

Ocean collapse triggered ancient wildfires, research suggests

Ocean collapse triggered ancient wildfires, research suggests Gaby Clark Scientific Editor Robert Egan Associate Editor Research led by the University of Alabama found that widespread wildfires during one of Earth's ancient environmental crises did not trigger an ocean collapse but were a consequence of it. The study, published in Science Advances in April, revisits the Late Devonian period, when large parts of the coastal ocean became oxygen-depleted, disrupting marine ecosystems on a...

Cold-grown plankton shells sharpen Arctic climate reconstructions

Cold-grown plankton shells sharpen Arctic climate reconstructions Sadie Harley Scientific Editor Robert Egan Associate Editor Researchers at iC3 have found a way to improve records of past high latitude ocean change using tiny plankton shells called foraminifera. By growing these foraminifera under controlled cold-water conditions, the team has extended a key temperature tool into the range most relevant for subpolar and polar oceans. The study's results matter for anyone using marine...
